ArenaNet announces they are accepting signups on this page to participate in upcoming Guild Wars 2 beta testing events. The bad news is the site seems to be suffering under the load from this, but the good news is they are accepting applications for the next 48 hours, which will hopefully provide sufficient opportunity for everyone to sign up. Word is this is for "one of the upcoming Guild Wars 2 beta events," and signups close at 18.00 GMT on Friday. They also explain: "These special closed beta events are open to invited players only. Everything you see in the game is still confidential, so we’ll require you to sign an NDA (non-disclosure agreement) in order to play." They say to expect a FAQ soon explaining more of what this will involve.

It IS an MMO as far as genre/gameplay type, except the open areas are instanced so that only you and your party are in it. That's why there's no subscription fee; they needed far fewer servers to run it. People that say it's not an MMO are arguing over semantics, basically (Uh-uh, it's not massively multiplayer if the only place you see other people is in town!). So why then do people describe something like Kingdoms of Amalur as a "single-player MMO?" Because the term has come to represent more than its acronym.
